Abstract: Techniques disclosed herein relate to glucose level measurement and/or management. In some embodiments, the techniques involve obtaining in vivo characteristics of a glucose sensor predicted using fabrication process measurement data associated with the glucose sensor, the in vivo characteristics including an in vivo sensitivity, an in vivo intercept, or a combination thereof; receiving sensor measurement data measured by the glucose sensor, the sensor measurement data including sensor current (Isig), counter voltage (Vcntr), electrochemical impedance spectroscopy (EIS) data, an age of the glucose sensor, or a combination thereof; and estimating a sensor glucose (SG) value using an SG model, wherein input parameters of the SG model include the in vivo characteristics of the glucose sensor and the sensor measurement data, and the SG value is an output of the SG model.
